AUTOMATIC GRAIN-WEIGHING MACHlNE.

SPECIFICATION forming part of Letters Patent No. 323,533, dated August4, 1885.

Application filed April 15, 1884.

(N0 model.) Patented in Belgium December 15, 1883, No. 63,551, and inEngland January ll, 1884 To all whom it may concern:

Be it known that l, CARL REUTHER, asubject of the Emperor of Germany,residing at Hennef, Prussia, Germany, have invented certain new anduseful Improvements in Automatic Balances for Fine-Grained andPulverized Materials, and for Liquids, of which the following is a full,clear, and exact description.

This invention is an improvement upon the device patented to me July 18,1882, No. 261,257. To distinguish clearly what I deem to be new in thisinvention I have illustrated in Figure 1 the construction set forth insaid patent, and in the remaining three figures the improrementthereon.Accordingtothatpatent, (see Fig. 1,) the trap F was perforated and wasadaptedto close and shut off the volume of grain when the charge in thereservoir was nearly complete, and the grain slowly passed through theperforations until the traps G closed outside of the trap F andcompletely shut off the supply. This outer trap, G, was connected with atumblingbob or crampweight Pp, the function of which was to control thefirst of the movement of the reservoir B in either direction. Thereceptacle B was loaded during the small supply through the openingsf inthe trap F with the pressure eX- erted upon the cup h by the knife-edgez. The beam A would consequently commence to sink on the receptacle sidebefore having received the full charge, and this exactly as much sooneras corresponded to the adjustment made upon the cramp-weight. Thisadjustment was made by a screw, 1) which passed through a nut, p andallowed the weight 1) to be thrown more or less from a center ofgravity.

In the present invention I do away with the trap G and employ a slideentirely separate from the cramp-weight, and instead of perforating thetrap F, I perforate the brush (1 and arrange the slide along itsvertical side. I also provide for more or less resistance to be giventhe cramp-weight. These features are illustrated in the drawings, inwhich- Fig. 2 is a side elevation with parts re moved to show the newconstruction and arrangement with the weighing apparatus at rest. Fig. 3is adetail view of port-ions, showing the action of parts when thereceptacle is loaded and the beam tipped, and Fig. 4 a view of amodification of the means for adj ustably weighting the crampweight.

Referring to the drawings, A designates the beam, B the receptacle, andO a vertical frame by which the said receptacle is suspended by aknife-edge from said beam. D designates the hopper, F the trap orcut-off, and (Z the brush. These parts are substantially of theconstruction and arrangement shown in my patent hereinbefore mentioned,except that the trap F is imperforate, and that the necessaryperforations for slow feed are transferred to the brush, which isarranged parallel with the track of a slide cut-off G, which actsagainst the inclined brush (1. This slide G is hung upon a verticalframe, J, which carries also a knife-edge, J, and has knife-edgeconnections J with a weighted lever L, as shown. The frame J andslideGare arranged to travel with the receptacle end of the beam, andthe weight V on the beam L serves to adjust the bearing on the beam A inthe same manner that the devices 19 p served in the previous patent.

p designates the cramp-weight, and it earries an arm, q, which restsunder a lug or pin, n, on the frame 0. In a condition of rest the saidcramp-weight lies in contact with a stationary lug, m, upon the mainframe, and when the frame 0 is depressed by reason of the weight ofgrain in the receptacle the pin it depresses the arm (1 until the weighthas passed to the other side of the center of gravity, when thecramp-weight falls against the stop a and remains in that position, asseen in Fig. 3, until, the grain having been automatically dischargedfrom the receptacle by the devices shown in the previous patent, theframe 0 again rises and carries the cramp-weight over to its normalposition. The pin ais arranged at such distance from the arm qthat thecrampwcight will not be thrown until the slide G has completely closed.\Vhen the crampweight falls over to the right, the arm q serves to forcedown the balance-beam, and this carries the receptacle with it.

The pressure of the slide G and its support ing parts is partlycompensated by the lever L and its adjustable weight. Instead of thesedevices, however, I may use. a cup, G, and small weights, as shown inFig. 4.

The improvements in this invention will be seen to consist, first, inthe separation of the cut-off G from the cramp-weight; second, inperforating the brush d, providing a separate brush, (1, and a slidingcut-off in connection therewith, and in closing the cut-off F.

Vhat I claim as new is 1. The combination,with the beam A, cut-off F,brushes (Z d, and slide G, of the balancing means L V, the cramp-weight,and their connections, all arranged and operating as and for thepurposes set forth.

2. The receptacle B, beam A, perforated 15 brush and cut-off, combinedwith the frame 0, having lug n, the cramp-weight p q, slide G, brush (6,lug m, and means, as L V, for adjusting the pressure on the beam, as setforth.

In testimony whereof I have hereunto set my hand, at Cologne, this 20thday of December, 1883, in the presence of two subscribing witnesses.
